I Application filed June 6, 1902. Serial No. 110,518- (No model.)

To all whom, it may. concern.-

Be it known thatLMA'NLEY KELLEY, a citizen of the United States, residing at 0010, in the county of Story and State of Iowa, have invented certain new and useful Improvements in Ohurns, of which the following is a specification.

For a full description of the invention and the merits thereof and also to acquire a embodying the invention.

knowledge of the details of construction of the means for effecting the result'reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic fea tures of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in whicH- Figure l is a perspective view of a churn Fig. 2 is a vertical central longitudinal section thereof. Fig. 3 is a transverse section about on the line X X of Fig. 2. Fig. 4 is a detail view of the operating-gearing on a larger scale. Fig. 5 is a detail View of the clutch. Fig. 6 is a detail view of a portion of one of the heads and the corner portions of adjacent sides, the parts being separated and arranged about in'the position which they will occupy when assem-- bled.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The churn-body is polygonal in form and maycomprise any number of sides, depending upon its capacity, and is rotatably mounted. Blades or wings 1 extend inward from the sides 2 of the body and incline with reference to the axis and are spaced at one end from the proximal head of the churn-body. By having the blades or wings I inclined throughout their length the butter is carried upward and permitted to drop, while at the same time being moved from one end of the churn toward the opposite end, thereby insuring the bringing of every portion into position for treatment. These blades or wings are of especial advantage in working the butter, as theyobviate the breakiugof the grain, which is the chief objection urged against butterworking machines generally used. Heads 3 are of like formation and correspond to the polygonal form of the churn-body in transverse section, and the sides 2 are attached to corresponding edges of the heads and overlap at their edges, which are correspondingly grooved to receive keys or locking-strips at, by means of which tight joints are provided. The sides 2 have transverse grooves in their inner faces and near their ends to receive the heads which are let therein. Segments 5 are fitted to the end portions of the sides 2 about in the plane of the heads 3 and are grooved in their outer edges to receive circular ties 6, by means of which the parts are securely joined, the end portions of the ties being threaded to receive nuts 7 after being passed through openings in the bent ends of coupling-lugs 8, seated in one of the segments. Access is had to the interior of the churnbody through an opening in one of the sides 2, which is closed by means of a cover 9, provided near its ends with oppositely-disposed cams or inclined surfaces 10 for cooperation with a bar 11, pivoted intermediate at its ends to the cover 9 and adapted to engage under cleats l2,=provided upon the side having the opening at the ends of the latter, said cover being forced into place by the cams or inclined surfaces 10, as will be readily comprehended.

The frame for supporting the churn and its operating-gearing may be of. any conend of said journal and is provided upon one side with cog-gearing 18, formed upon the outer surface of a laterally-extended rim, the inner surface of said rim being smooth and forming one element of a clutch of the friction type. A guide is secured to the journal carrying the band-pulley and comprises a hub 19 and oppositely extended pins 20. Shoes 21 are siidably mounted upon the end portions of the guide and constitute the gripping elements of the clutch and are adapted to cooperate with the aforementioned annular clutch member. A collar 22 is slidably mounted upon the outer end of the extended journal and links 23, connected with the shoes 21. A shipper-lever 24. has its forked end extended into the annular groove of the collar 22 and is adapted to throw the clutch into and out of operation. \Vhen the lever 2A is operated to move the collar 22 outward, the clutch is unshipped and the band-pulley is adapted to run freely upon the journal; but when the collar 22 is moved inward the clutch is thrown into active operation and the bandpulley 17 and its journal rotate together and cause the churn-body to correspondingly move to efiect a churning of the butter.

For operating the churn at a slower speed the following instrumentalities have been devised, and consist of the shaft 25, arranged parallel with the extended journal 15 and mounted in bearings applied to a bracket extension 26, forming a part of the framework and attached to the standard supporting the extendedjournal. Theshipper-lever24isfulcrumed to the bracket extension 26. A gearwheel 27 is mounted upon the inner end of the shaft 25, so as to turn therewith and slide thereon, a shipper-lever 28 being provided for moving the gear-wheel 27 upon the shaft so as to throw it into and out of meshing relation with the gear-wheel 16. Another gear-wheel,29,is mounted upon the outer end of the shaft 25 to turn therewith and slide thereon and is operated by means of a shipperlever 30, which, with the shipper-lever 28, is fulcrumed to the bracket extension 26. The gear-wheel 29 is adapted to be thrown into and out of gear with the cog-gearing 18. When the gear-wheel 27 is in mesh with the gear-wheel 16, the gear-wheel 29 is in mesh with the cog-gearing 18 and the clutch is unshipped. Hence the churn-body is rotated through the intervention of the shaft 25 and the cooperating gearing. The diameters of the gear elements 16, 18, 27, and 29 are such as to admit of driving the churn at a slower speed than if operated directly from the bandpulley when clutched to its supporting-journal. For working the butter it is preferred to operate the churn more slowly than for churning. Hence the provision of the slow gearing.

This churn is readily accessible for cleaning, every part being within reach of abrush, so as to be scrubbed, thereby insuring perfect cleanliness, which is absolutely necessary in machines of this character to avoid contamination of the product.

Having thus described the invention, what is claimed as new is- In a churn, a polygonal churn-body, segments applied against the outer sides of the churn-body and unitedly forming a circle, a circular tie encompassing the churn-body and segments, and means for drawing the ends of said tie together, substantially a specified.

In testimony whereof I affix my signature in presence of two witnesses.

MANLEY KELLEY.
